The Who frontman Roger Daltrey regularly tried to persuade late bandmate JOHN ENTWISTLE to quit drugs and alcohol, but his pleas fell on deaf ears.
Daltrey and his only surviving bandmate, Pete Townshend, were devastated when Entwistle died of a cocaine-induced heart attack in a Las Vegas hotel room in 2002.
His death came 24 years after drummer Keith Moon took a fatal overdose of Chlormethiazole in a London flat.
Daltrey tells British magazine Radio Times, "John was a harder nut to crack than Keith - that's why we called him The Ox.
"He kept going a lot longer than Keith and we thought we were going to save him so many times. But John was very happy being the way he was and age didn't change that."
The Who guitarist Townshend adds, "John was living the rock 'n' roll lifestyle - huge house, six deerhounds, nine rottweilers, a big recording studio.
"When he died, suddenly everything became clearer: It's just me and Roger now."
